A Connecticut woman says she thought she caught a bug when she developed stomach pains but ended up giving birth to a 9-pound-3-ounce boy without having known she was pregnant.

Jennifer Scollin gave birth Saturday morning in an ambulance parked in the driveway of her home in Seymour after her boyfriend, Matt Dillman, called 911 when the couple realized they were having their second child. Both mother and son were discharged from a hospital Monday and are doing fine.

Scollin told the Connecticut Post that there were no signs of a pregnancy. She said she had been feeling fine up until Saturday and had been menstruating every month until last month.

The couple named the boy Cole Michael Thomas Dillman, who joins his 4-year-old sister, Kelsey.
